思考：过去进行时用什么样的时间状语呢？
when 和 while 用法小结
相同点： when 和 while 都可以作从属连词。 引导时间状语从句。 都有“当……的时候”的意思。
指时间段，也可以指时间点
可以是延续性动词，也可以是终止性动词
when & while
我们都可以引导时间状语从句
我既可以接延续性动词也可以接非延续性动词。
When the rainstrm came, he was reading in the library.He finally fell asleep when the wind was dying dwn.When I was cleaning the windw, Mary was sweeping the flr.(少见）
表示两个过去的动作同时进行，这时更常用while连接。
当我在打扫卧室时，我妈回来了。My mther came back ________ I was cleaning my bedrm.
当他们到达时，正在下雨。It was raining ________ they arrived.
有时when可以代替while，而while则不能代替when。
when引导的时间状语从句中，从句的动作和主句的动作可以同时发生，也可以一前一后先后发生；while则强调主句和从句的动作同时发生。
when后面通常接一般过去时的从句，而while后接进行时态的句子。
玛丽在图书馆里读书时，杰克正在操场上踢足球。 Mary was reading in the library while Jack was playing sccer n the playgrund.
What is she ding nw?
She is ding her hmewrk.

eg：—When were yu dancing yesterday? —We were dancing at ten last night.
肯定回答：Yes, 主语+was/were.
否定回答：N, 主语+wasn't/weren't.
过去进行时的基本用法
eg：I was watching TV the whle night. We were having classes all day yesterday.
表示过去某一段时间内一直进行的动作，常与the whle day, all day yesterday等时间状语连用。有时没有明显的时间状语，可根据上下文语境判断。
eg：Miss Li was shpping at this time yesterday. I was lking fr my lst cat at nine last Mnday mrning.
表示过去某一时刻正在进行或发生的动作，与表示过去某一时间点的时间状语连用，如at 3 'clck yesterday afternn, at this time yesterday等。
when和while引导的时间状语从句
when和while都可意为“当……时”，用来引导时间状语从句，表示主句动作发生的背景。
when引导的时间状语从句
eg：When he was a child, he always tried ut new ideas.
表示主句动作发生的特定时间，既可指时间点，也可指时间段。
从句的谓语动词可以是延续性动词，也可以是非延续性动词；从句的动作和主句的动作既可同时发生，也可以是先后发生。

延续性动词和非延续性动词

eg：When I gt t the airprt, the guests had left.
从句位于主句之前或之后，当位于主句之前时，与主句要用逗号分开。

eg：The by will be a writer when he grws up.
while引导的时间状语从句
eg：While Linda was sleeping, Jenny was helping me with my hmewrk.
